The perimeter of a square is 4 times each side. If we have 1 square of 2 cm per side, the perimeter is 8 cm. If we place 1 square adjacent to the right side, the perimeter of the new figure is 12 cm. If we place 1 square adjacent to the right side of the previous figure, the new perimeter is 16 cm. If we continue this pattern, what would be the perimeter of 8 squares?

A 32cm
B 44cm
C 40cm
D 36cm

11 feet 6 inches and 8 feet 6 inches

yes yes yes yes yes yes yes yes yes

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
